Specification of Letters Patent.

Patented Nov. 28, 1911.

Original application filed March 28, 1907, Serial No. 364,960. Dividedand this application filed January 30, 1908. Serial No. 413,430.

To all whom it may concern:

Be it known that I, CHARLES F. PYM, a subject of the King of GreatBritain, residing at Essex, in the Provinceof Ontario, Canada, haveinvented an Improvement in Lasting-Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention relates to lasting machines, the present applicationbeing a division of the original application, Ser. No. 364,960 filedMar. 28, 1907 (now Patent No. 882,018,

patented March 17 1908).

One of the main objects of the invention covered by this divisional caseis to provide,

in connection with the lasting mechanism,

means for automatically drawing around the toe of the last a wire orother binder for holding the upper in place after being lasted, saidmeans preferably consisting .of a pivoted arm for carrying andstretching a wire around the toe of the last for holding the edge of theupper in place after the lasting operation is completed, and means forguiding said wire, into place as it is drawn about the too by said arm,whichis automatically operated in timed relation to the movement of thelasting wipers.

The invention herein set forth also relates to further details ofconstruction, arrangement and combination of parts whereby the wiringand subordinate operations are accomplished in a satisfactoryandexpeditious manner.

To fully disclose my invention I have shown not only the particularparts herein claimed, but suflicient details of the complete machine toenable fully the operation and construction thereof readily to beunderstood.

showing the parts in position to receive the shoe; Fig. 12 a perspectivedetail of the parts in position just as the wiring operation is'aboutcompleted; and Fig. 13 is a plan view of a last showing an insole andupper secured thereon and the top plate and binding wire in operativeposition.

Although my invention relates more particularly to the wiring or bindingmeans for securing the edge of the upper in place after the lastingoperation, it is necessary for a proper understanding of the wiringmechanism and the cooperating parts, to describe more or less of themachine and its general operations.

As shown in the drawings 1 is a suitable supporting pedestal upon theupper end of which is secured a bed or table 2 having suitable bearingbrackets 3 each having two bearings, one for a driving shaft 4 and theother for a driven or counter shaft 5, motion being transmitted from thedriving to the driven shaft by gears 6 and 7 which are in the proportionof three to one so that one revolution of the driving shaft will turnthe counter shaft but one-third of a revolution.

formed with a notch or shoulder 11 adapted to be engaged by a dog12'pivoted upon the bearing bracket and-operated by a rod 13 attached toa suitable foot pedal (not shown) to throw the dog out of engagementwith the notch and permit the clutch to turn the shaft. The drivingshaft is thus stopped by the dog at the end of each revolution and thedriven or counter shaft is stopped at three certain positions duringeach revolution, the operator controlling the starting of the machineeach time by the actuation of the dog.

Secured upon the counter shaft 5 are two wheels formed with. cam grooveswhich wheels I will call for convenience of description the rocker-cam14 and the push cam 15.

16 is a rocker-bar pivoted intermediate its ends and carrying on itstail end a roll 17 engaging the cam groove of the rocker-cam,

and at its forward end provided with an extended supporting guide way-18 for a push bar 19 which is adapted to slide longitudinally in saidway and is carried and rocked vertically by said rocker bar. Thispush-bar is also provided with a roll 20 which engages the cam groove inthe push-cam 15 and rigidly secured to it near its forward end is adepending post 21 to the lower end of which are pivotally attached thecrossed levers 22 at their point of intersection. To the forward ends ofthese levers 22 are pivotally attached the wipers 23 which consist oftwo hinge connected plates formed at their adjacent edges to conformapproximately to the outline of either the heel or the toe of the shoeand these wipers turn freely within slots cut in the ends of said leversupon pivot pins 24 extending through said levers and wipers and are thusheld so that they may be quickly and easily removed and other wiperplates having a different form inserted to more nearly conform to theparticular shape of toe or heel to be lasted. In this machine it is not,however, necessary as will be hereinafter more fully set forth, tochange these wipers in lasting the different sizes of substantially thesame form but only when there is a radical change in the form, as from around to a very pointed toe or from toe lasting to heel lasting or fromladies to gents shoes, etc.

The rear ends of the crossed levers are connected by a plate 25 securedto the forward end of a bar 26, which extends rearwardly throughbearings 27 secured upon the table 2. The said plate is provided nearits ends with forwardly converging slots 28 through which the pins orbolts 29 connecting the levers to said plate pass and slide freely, andsleeved upon the bar 26 between the bearings is a coiled spring 30engaging the forward bearing at one end and a collar 31 on that bar atits opposite end to normally resist the forward longitudinal movement ofsaid bar in its bearings, a second collar 32 on said bar forward of itsfirst bearing serving to limit the rearward movement of said bar in itsbearings. A joint 33 in said bar is provided to permit the up and downmovement of the wipers, which movementis caused by the rocker-bar.

When the push cam 15 moves the push-bar forward, the pivotal point ofthe crossedlevers is moved forward by the post 21 and this movement byreason of the forwardly converging slots in the plate 25 causes the endsof the levers to move toward each other and close the wipers inward, thespring 30 on the bar 26 holding said plate against any forward movementunless the resistance to the closing of the wipers, caused by theircontact with the shoe, is sufficient to overcome the resistance of saidspring, when the ward movement of said plate, which movement bylessening the movement of the pins 29 in their slots, will lessen thedistance which the wipers will be closed by a given forward movementimparted to the push-bar by its cam. The wiping force of the wipers isthus regulated by the tension of said spring which may be adjusted bythe collar 31 and will be the same regardless of variations in the toesor heels of the shoes operated upon.

Secured upon the table 2 is an upwardly and forwardly extendingbracket-arm 34 the forward end of which is provided with guide lugs 35through square openings in which a presser-bar 36 slides. Forconvenience in operating the machine this bar is set in a downwardly andforwardly inclined position and is normally held against movement in itsbearings by a coiled spring 37 sleeved thereon between said guide lugsand engaging the upper lug at one end and a collar 38 adjustably securedupon the bar at its opposite end. A second collar 39 on said bar belowthe lower guide lug is provided to limit the upward movement of saidbar. The lower end of said presser bar is roughened or formed with teethto engage the sole over which the upper is to be lasted, at somedistance from the toe or heel of the last, and adjustably secured in atransverse hole in said bar by a set screw 40, is a presser arm 41extending rearwardly of the machine and formed with a downwardly curvedand toothed end to engage the shoe sole at a point near the end of itstoe or heel. The adjustment by means of the set screw 40 varies theangle or plane of engagement of the presser bar and presser arm. To holdthe last upon which the shoe is secured in position for lasting, upagainst these two points of contact, namely the ends of the presser barand presser arm, an automatically operated jack 42 is providedconsisting of a bar 43 guided in openings in bearing ears on a bracket44 secured to the end of a supporting and operating bar 45 which ispivoted intermediate its ends to a convenient stationary part of thesupporting frame of the machine and is provided at its extreme rear endwith a roll 46 to engage the cam surface of an outside cam 47 securedupon the countershaft 5.

Between the bearing ears of the bracket 44 a coiled spring 48 is sleevedupon the bar 44 and engages the lower end at one end and a collar 49adjustably secured upon the bar, at its opposite end, to yieldinglysupport the bar in its bracket, and a second collar 50 is secured uponthe bar below the lower ear to limit the upward sliding movement of thebar in its bearings. On the upper end of the bar is a curved seat 51 forthe last, shaped to conform to the surface thereof just forward of theinstep and support the said last at a point intermediate the points atwhich the presser bar and arm engage the sole and thus firmly clamp thelast between said bar and arm above, and the jack below, said jack beingraised to so clamp the last, in timed relation to the movement of thewipers and other parts,

by the jack-cam 4:7. The toe of the last is thus firmly clamped and heldbetween three points of contact in position for lasting and when placedin the machine by the operator it may be adjusted laterally thereon tobring the toes of lasts having various lines of swing in the properrelation to the wipers, and by providing the springs 37 and 48 toyieldingly hold the presser bar and jack, respectively, the last isclamped between members which will yield vertically to accommodate lastsof various thicknesses and to permit the wipers to swing downward afixed distance regardless of the thickness of the last. The spring 37 ismade lighter than the spring 48 so that when the last is clamped betweenthe jack and'presser-bar with the wipers out of contact with the last,the spring 48 will overcome the spring 37, moving the presser bar upwarduntil the collar 39 engages the lug 35 which collar is adapted to beadjusted so as to stop the last in its upward movement in the properrelation to the wipers to permit said wipers when raised, to beprojected over the edge of the sole.

A rod 52 is attached at its upper end to the lower end of thebar 43 ofthe jack and at its opposite end to a double foot lever 53, the rodbeing pivoted to the foot lever at one side of the pivot of said leverso that the operator by placing his foot upon one end of said lever maydraw the said bar downward against the action of its spring to releasethe last at any time during the lasting operation, and by placing hisfoot upon the opposite end of said lever the jack may be lifted toincrease the clamping pressure.

In order that the leather of the shoe upper which is being lasted may bestretched tightly over the heel or toe of the last and at the same timeheld against any possibility of wrinkling during the lasting operation,a clamping foot 56 is provided to engage the inner curved side of theprojecting edge of the upper at the heel or toe of .the shoe and clampsaid edge between it and the forming or wiping edges of the wipers. Thisfoot is pivoted at its upper end to the forwardly projecting end of thepush-bar 19 and at its lower end is provided with laterally extendingcurved portions 57 so formed on their outer side as to substantiallyconform to the outline of the heel or toe of the shoe and thus firmlyhold said edge against the wipers without altering the curve which theleather naturally takes when tackedupon the last in the usual manner.Pivotally attached to one side of the post 21 is a guide block 58 havinga transverse hole in which a rod 59 is adapted to slide freely. This rodis pivotally attached at one endto the foot 56 intermediate its ends,and sleeved thereon between said block and an adjusting nut 60 on itsopposite end is a coiled spring 61 which normally acts to swing the footdown against the formed edge of the wipers and clamp the edge of theleather between. By adjusting the nut 60 the tension of the spring isincreased or diminished to increase or diminish the clamping power ofthe foot. A latch-bar 62 is pivoted intermediate its ends upon the topof the rearmost bearing 27, the forward bearing serving as a stop tolimit the falling of the forward end of said latch-bar which is normallyheld against the stop by a coiled spring 63, and said forward end isadapted to engage the rear end of the rod 59 upon the rearward anddownward movement of the forward end of the push-bar to which theclamping foot 56 is attached and cause said rod to slide through itsbearing block against the action of said spring, turning the foot on itspivot and swinging it upwardly and forwardly away from the wipers, asshown in Figs. 1 and 11. Upon the large gear wheel 7 on thecounter-shaft 5, is a pin 64 projecting from the side thereof, shown inFig. 3, and this pin is so set that at the proper moment it will engagethe rear end of the latch bar and, tilting the same, raise its forwardend out of engagement with the rod 59, releasing said rod and permittingthe spring to act to throw the foot into clamping position.' In certainkinds of work, the edge of the upper is held in place at the center ofthe toe by a tack, as shown in Fig. 13, and as it is not desirable toremove this fastening, the foot 56 may be cut away or provided with anotch 65 at its center if so desired, to permit of thus fastening theupper at the toe of the last.

To hold the edge of the sole over which the upper is being lasted,firmly down upon the last so that it will not be displaced by the wiperswhen they are forced over and upon said edge, a toe plate 66 is slidablyattached to the pressure arm 41 by a screw 67 extending through alongitudinal slot in said plate, and the lower end of this plate isbroadened out and curved in such a manner that its edge is adapted toengage the sole close to the edge thereof around the toe, and, beingattached to the presser-arm, presses firmly down upon said edge. Theplate is projected downwardly to engage the sole, by a coiled spring 68sleeved on the presser-arm between the presser-bar and the forward endof said plate which is turned upwardly to form a lug 69 adapted to beengaged by the laterally bent end of a stoparm carried by the post 21,when said post is moved forward by the push-bar to carry the wipers overand down upon the edge of the shoe sole. Said toe plate is thus moved onthe arm against the action of the spring 68 out of the way of the wipersas they move forward. A notch 71 may be provided in the toe plate, asshown in Fig. 13, to permit the upper to be tacked to the insole at thecenter of the toe, if so desired.

To effectually secure the edge of the upper in place after the lastingoperation is completed, a wire is stretched tightly around the toe incontact with the lasted edge, its ends being made fast to tacks driveninto the sole, and to automatically so place the wire and draw it tight,said Wire, which is supplied from any suitable spool indicated at 72 inFigs. 8 and 9, is passed through any suitable tensioning device 73, thenthrough the loop formed by the curved guide finger 7 1 and its endfastened to a tack driven into the sole near the left hand edge thereof.A supporting arm 75 is rigidly secured at one end to the lower end ofthe post 21 below the wiper levers, and to the free end of this rigidarm is pivoted a curved arm 76 having a grooved roll 77 at its free endwhich engages the wire midway between its secured end and the tensiondevice. To the curved arm is pivotally attached at one end, an operatingrod 78, and the opposite end of said rod is attached to the lower end ofa lever 79 which is pivoted at its upper end to the stationary bracket34: and connected intermediate its ends to the push-bar 19, so that uponthe forward movement of said pushbar the lever 79 is swung on its pivotand turns the curved arm 7 6, carrying its roll upward and over the lastforward of the presser bar to stretch the wire around the toe, the wirebeing guided to place close up beneath the wipers at their forward edgesby the guide finger 74 which is rigidly se cured to the supporting armand curved downward therefrom thence upward to form a loop, with itsfree end close beneath the wipers and adjacent to their formed or wipingedge. Any desired number of these guide fingers may be used or the formmay be changed as desired.

In Figs. 1, 8 and 11, the parts are shown in posit-ion to receive theshoe to be lasted and Figs. 5, 6 and 7 are diagrammatic illustrations ofthe actuating cams showing their relation to each other and to the otherparts when said parts are in the position shown in the first namedfigures or when the rolls engaging said cams are in position a asillustrated in said Figs. 5, 6 and 7. lVhen the parts are in theposition shown in said Figs. 1, S and 11, they are at rest with the jack42 down, the roll 16 being in contact with the small part of thejack-cam; the

wipers in their lowest position, the roll 17 on the rocker-arm being incontact with the concentric inner part of its cam groove; and thepush-bar carrying said wipers, in its rearmost position, the roll 20being in the innermost portion of its cam groove. As illustrated in Fig.11, the operator places the last with the shoe sole firmly up againstthe presser-bar and presser-arm, and the toe plate engaging said soleclose to its edge with the projecting edge of the upper eX- tending upadjacent to the wiping edge of the wipers. As shown in dotted lines inFig. 1, the pin 64 is just in contact with the rear end of the latch-bar62 and when the operator starts the machine by actuating the dog 12 torelease the member 10 and permit the clutch to operate to turn thedriving shaft, the first movement will rock said latch-bar and releasethe clamping foot 56 to clamp the edge of the upper to the edge of thewipers. At the same time the jack is raised by the turning of thejack-cam and the last is firmly clamped between the jack and thepresser-bar and presser-arm. \Vhen the driving shaft has made onerevolution, it is again stopped by the dog 12, the cams having beenturned one-third of a revolution or to position b which turning hasraised the wipers slightly and projected them forward ashort distance,the cam grooves in the rocker and push cams being slightly farther fromthe center of the cam at this point. While the machine is at rest inposition I) the operator threads the securing wire over the groovedpulley on the curved arm 7 6 and through the loop of the guide finger 74and secures its end to a tack in the shoe sole. The wire may however besecured to the tack before the last is placed in the machine. Themachine is then again started by releasing the dog 12 and during thisrevolution of the power shaft and the turning of the cams from positionb to 0 the jack is firmly held up to place by the large concentric sideof the jack-cam; the push-bar is projected to the forward limit of itsstroke carrying the wipers forward and at the same time closing them,carrying the rear end of the actuating rod for the clamping foot pastthe forward end of the latch-bar, engaging the stop arm 70 with the lugon the toe-plate and moving said plate out of the path of the wipers,and turning the curved arm on its pivot to stretch the wire around thetoe and carry it forward operation or position 0. While the parts are atrest in position 0, the operator severs the securing wire and makes itfast to a tack driven into the sole near the right side thereof, andupon again starting the machine by releasing the dog 12, the jack atonce falls, releasing the shoe; the push-bar is retracted causing thelatch-bar to raise the clamping foot, moving the wipers to theirrearmost position, moving the stoparm out of engagement with thetoeplate, and swinging the wire-arm backward; and the rocker-bar is heldin its lowered position. The cycle of operation is thus completed andthe parts are again in position to receive another last. The stoppingmechanism permits the mechanism to stop automat-ically at each criticalpoint.

It is obvious that if the operator holds the dog 12 out of engagement,the operation of the machine will be continuous and when he has becomevery proficient in the manipulation of the machine it will be necessaryfor him to stop the machine only to remove the lasted shoe and putanother last in position.
